Consistency is the key and no cheating - Liz Plan and Goals

My biggest problem is staying consistent with my exercise and eating habits. I give myself a schedule to follow through out the week, like doing a different exercise every other day and doing them on and off through out the day. Then comes the cheating "oh, i can count that as my exercise!" , or I will do an extra exercise so I can eat this, and then I never do. So basically i am just cheating myself.                                                                                                 
My Goal  is to lose 15 pounds to get to my healthiest weight and to be in shape.                                                                                            
 My Plan is to eat right and watch my portions. Be consistent with exercise and NO CHEATING.
